Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] In the mineral crushing process, various types of mills are mainly used for fine particle crushing. With the increase of mineral processing capacity in mines, the application of large grinding equipment such as semi-autogenous mills is becoming more and more extensive. This type of grinding equipment usually has a large geometric size and strong mineral processing capacity, b...

Abstract

The invention provides a method, device and electronic equipment for measuring the grinding state of a mill, including: obtaining the state parameters of the target mill on the current working day; determining the throwing movement of the outermost grinding medium inside the target mill according to the state parameters The coordinates and impact angle of the impact point; determine the mineral distribution ore angle inside the target mill according to the estimated value of the pre-set mixing filling rate in the target mill and the ratio of the actual mill speed to the critical mill speed; according to the impact angle, Mineral distribution mine toe angle and pre-established judgment model determine the grinding state of the target mill in the current working day. The present invention can effectively improve the existing on-line measurement method of the grinding state of the mill, and intuitively display the grinding state of the mill.

Description

technical field [0001] The invention relates to the technical field of on-line detection of mineral processing, in particular to a method, device and electronic equipment for measuring the grinding state of a mill. Background technique [0002] As one of the core processes of the mineral processing process, the mineral crushing process mainly uses various types of mills for fine particle crushing operations. With the increase of mine mineral processing capacity, the application of large grinding equipment such as semi-autogenous mills is also more extensive. At present, the online analysis of the grinding state of semi-autogenous mills usually relies on experienced operating experts to make comprehensive judgments through motor current, shaft pressure, electric ear signals, vibration signals, etc. However, these signal values ​​are not strongly related to the grinding state in appearance, and cannot intuitively show the current working state of mineral distribution and crus...
